To alt whom 'it may concemq' Be it known that I J ABEZ H. HoDsKINsoN, acitizen of the United States, residing at Salem, in the county of Essexand Commonwealth of Massachusetts, .have invented certain Improvementsin Buiing-Machines', of which t-he following description, in connectionwith the accompanying drawings, is a specification, like referencecharacters on the dra-wings indicating like parts in the severalfigures.

This invention relates to buiiing machines and particularly to machineswhich are adapted for finishing boots and shoes and in which an abradingdevice, such as a sheet of sandpaper is secured to a holder carried by arotatable spindle. In using the machine anabrading device soon becomesworn and untit for .further use and has to be replaced. In machines asheretofore constructed it has been necessary to disconnect the machinefrom its driving mechanism, wait for the spindle to stop rotating, thenrelease the worn abrading device and replace it by a new one, andfinally connect the machine .again with its driving mechanism and wait'for the spindle to reach its normal speed before presenting another shoeto be buffed'. Asl this procedure has to be repeated many times during adays work much time is lost and the capacity of the machine ismaterially reduced.

.the abrading device from the rotating spin dle by which it is carried.In the preferred embodiment of the inventionl herein shown the holder isconnected with its spindle by a latch which has a coupling pin and whichrotates with one of said parts, and a manually operable device isprovided in the form of a hand lever which is normally held out ofposition for engagement with the latch, but which may at any time whilethe machine is running be moved into position to be engaged by thelatch. The latch is provided with an inclined face for engaging the handlever and when the lever is placed in the path of the latch the latch isautomatically actuated in the direction to release the holder from thespindle. If the latch is carried by the holder the engagement with thehand lever will serve to check the rotation of the holder when it hasbeen disconnected from the spindle and will hold the coupling pinwithdrawn during such engagement.

In accordance with another feature of this invention provision is madewhereby the holder is automatically separated from the spindle when thetwo parts-have been disconnected. As herein shown, the spindle isarranged in vertical position and the holder is suspended from the lowerport-ion of the spindle and when it has been disconnected from thespindle is free to'move downwardly away from the spindle by gravitation.desired a device may be provided to separate or assist in separating theholder and spindle when they are disconnected.

In a modified construction the stem of the holder is journaled in abearing in the machine frame and is normally connected to the spindle bya clutch, and means is provided under control of the operator by whichthe clutch may be operated at any time while the machine is running todisconnect the spindle from the stem of the holder. Preferably means isprovided for maintaining the spindle and the holder in the relativepositions to which they are moved for disconnecting them. As hereinshown the spindle is arranged for longitudinal movement with relation tothe stem of the holder and a manually operable lever has one endarranged in a peripheral groove inthe spindle for moving the spindlelengthwise toward and from the holder. The spindle carries one member ofthe clutch while the other member is carried by the stem of the holder,and as herein shown one member of the clutch is provided with a couplingpin to interlock Awith the 'walls of any one of a plurality of toconnect the two members of the clutch and a latch is arranged to holdthe lever in the position to which it is moved for separating themembers of the clutch. Preferably the clutch member carried by the stemof the holder has frictional engagement with a fixed part by which therotation of the holder is checked when the holder has been disconnectedfrom the spindle. The holder may thus be quickly brought to rest andthen the worn abravding device may be removed. andf a new one put in itsplace without taking the holder fromthe machine.v

A further objectY of the invention ris to facilitate the removal of wornabrading devices from the holder and the application of .new abradingdevices to the" holder. `rTothis end a feature of the`inventionjconsists in a securing device detachably connected with t-heholder and arranged', to be automatically moved toward position',to'permit vthe abra-ding device to be taken out. As

herein shown, the securing device comprises a member :for clamping theabradin'g'vdevice against a portion of the holder, and a memberconstructed and arrangedto be fastened to or intrlocked with the holder.vr'In one embodiment vherein shown of this-- feature of the inventionthe securing device kcomprises a headed bolt arranged toextendfcentrally through ya disk of abradingv .material, the headclamping the abrading materiale `ainst the holder while -the shank yofthe bo t eX- tends into the holder and is interlo'cked there with. Aspring is arranged togforce the bolt outwardlywith relation toy theholder when the bolt is disconnected from the holder.

The abrading device is thus [immediately unclamped as soon as the boltis unlocked from the. holder. In accordance with one constructionembodying this invention the interlocking engagement between the holderand the securin device is made by a bayonet joint. Prefera ly the holdercomprises a stem -which is centrally `recessed to receive the shank ofthe securing device and is protightly. The movement of the clampingmember maybe effected by a collar arranged to turn in the member withoutrelative longitudinal movement and having screw-thread` ed engagementwith the-,stem of the collar whereby when the securing device has beeninterlocked with the stem the clamping member may be forced downwardlyin the holder to grip the abrading device against the head of thesecuring device. In another construction embodyin this. invention'thesecuring device is rigldly connected with the stem or shank of theholder'. In this construction yielding means is provided for forcing theholder downwardly along the Stem whereby the abradi'ng device isautomatically clamped between said -holder and fthe head ofthe securingdevice. To facilitate the insertion and removal of abrading devicesmeans ,isl provided for'locking the clamping member` in aposition inwhichl the abrading device isunclalnped.

` These and other features of the invention, including certain detailsof construction and vcombinations of parts, will be explained in thefollowing `description and 'pointed out in the claims.

In the accompanying drawings, which show embodiments of the' severalfeatures of this invention, Figure 1 is a side elevation of so much of abufiing machine as is necessary for illustrating the present invention;Fig. 2 isa similar view showing a slightly modified arrangement, landthe parts in the position they occu y when the holder is being detachedfrom t e machine; Fig. 3 is a section on the line 3-'3 of Fig.` 1; Fig.4 is afsection on the line 4 4 of 4ig. 2; Fig. 5 is a section on theline 5 5 of Fig. 1; Fig. 6 is a perspective view of the securing deviceshown 1n Fig. 5; Fig. 7 is a side elevation of a modification; Fig. 8isa perspective view of the clutch shown in Fig. 7; Fig. 9 is a section onthe line 9-9 of Fig. 7; Fig. 10 is a. section on the line 10-10 of Fig.7 Fig. 11 is a side elevation of a portion of the securing device shownin Fig. 10; Fig. 12 is a further modification.

The spindle 2 is arranged for rotation in a suitable bracket 3 which maybe attached to any usual support and a pulley 4 is mounted on thespindle by means of which it may be continuously rotated. In theconrstructionshown in Fig. l the lower portion of the spindle is formedwith a central longitudinal opening to receive the reduced upper end ofstem 6 of the holder. The stem is provided with a recess 8 and thespindle carries a latch comprising rocking cam 10 shown as pivoted in acollar 12 on the spindle and having a coupling pin 14 to enter therecess in the stem, as best shown in Figs. 1 and 8. In' Figs. 2 and 4the latch is shown as carried by the stem of the holder which lits overthe spindle, the latter having the recess to receive the coupling pin14.y The latch is normally held by a spring 16 in position to retain thecoupling pin in the notch of the stem 6.' The rear arm of the rockingcam 10 is provided with inclined faces whiclrproject outwardly beyondthe collar 12 into position to engage during the rotation of the spindlewith any suitable device interposed in their path for o rating the latchto disconnect the holder rom the spindle. As herein shown, a manuallyoperable device 20 in the form of a hand lever is supported by one'of.the bearings in which the spindle rota-tes and is arranged to be movedinto posit-ion to be engaged by one of the inclined faces of the cam asthe spindle turns. The hand lever 20 is shown as n `normally held by aspring 22 in av position of the spindle. Preferably and as shown inFigs. 1 and 2, the holder is'supported entirely by the spindle, and whenit is disconnected from the spindle it is free to move downwardly bygravitation away from the spindle where it will be caught by theoperator and manipulated to replace a worn abrading device with a newone. While, as herein shown, the holder moves by gravitation away fromthe spindle when it is disconnected therefrom, a spring or other meansmay be employed for this purpose, as shown in Fig. l, between the end ofthe holder stem and the upper end of the recess in the spindle. In Fig.2 the collar 12a is shown as having 4an incline 13 on its upper faceadapted to be engaged by a shoulder 15 on the hand lever 20a whereby theholder is automatically forced downwardly during its rotation when ithas been disconnected from the spindle by operation of the latch. Thehand lever is also shown as provided with a shoulder 17 to stop thedescent of the holder and prevent it from falling from the machine. Thefriction of the hand lever against the periphery of the collar 12a andagainst the cam 10 will promptly check the rotation of the holder sothat when the hand lever is released the holder may fall into the handof the operator without any liability of injuring the hand.

In the modified construction shown in Figs. 7 and 8 the spindle 2isconnected to the stem 24 of the holder by a clutch comprising themembers 25 and 26, the member 25 being shown as a collar pinned to thespindle and provided vat its lower end with a peripheral flange having aseries of holes the walls of which are adapted to be engaged by acoupling pin 28 on the clutch member 26. In this construction thespindle is arranged for longitudinal movement with relation to theholder for carrying the clutch member 25 toward and from the clutchmember 26. To this end the spindle has a groove 30 near its upper endwhich is engaged by a lever 32 fulcrumed to a bracket at 34 and normallyheld-by a spring 36 in position to maintain the spindle depressed andthe clutch members in engagement. The spindle may be raised to disengagethe clutch members and disconnect the spindle from the holder bydepressing the outer end of the lever 32, and preferably means isprovided for holding the parts in this position. To this end the leveris provided with a swinging latch 38 normallyheld by a spring 39 inposition to y.engage the shoulder 40 on the bracket to which the lever32 is pivoted. By this arrangement the spindle may be disconnected fromthc holder and maintained in that relation without interrupting itsoperation and after the clutch members are separated the holder willreadily come to rest. It will be observed that with this constructionthe holder is not detached from the machine when it is disconnected fromthe spindle, but that it extends through one of the bearings of thebracket 3 and is held therein by the clutch member 26 and by a collar42.

Any usual or suitable form of holder may be employed with that portion'of the inments of different construction. In Figs. 1

and 5, is shown a ,holder comprising in addition to the stem 6 acylindrical member 50 movable vertically with relation to the stem bymeans of a nut 52 connected to the member 50 by a screw pin 54 whichextends into a groove 55 in 'the nut 52. The nut has screw-threadedconnection with the stem 6 and a stud 57 extending through the member 50into a Vertical groove in the stem holds the member 50 from rotarymovement, while permitting longitudinal movement with relation to thestem. As herein shown, the member 50 has connected to its lower end by ascrew 56 a block 58 to which is cemented a felt disk 59. lThe member 50with the attached block 58 and felt diskf) may be considered as a singlepart movable vertically upon the stem 6 foirclamping and unclamping theabrading device. Coperat- 'ing therewith for clamping the abradingdevice is a securing device, herein shown as comprising a clamping head60, for engaging the outer side of an abrading device 62 held againstthe lower face of the felt disk 59, and a shank 64 by which itis securedto the stem 6. For connecting the securing device to .the stem' 6 theshank .is provided with a longitudinal groove 65 having at 66 alaterally oiiset portion, herein shown as inclined toward the end oftheshank. The stem' 6 is centrally recessed to receive the shank 64 and isprovided with a lug 68 eX- tending into the central recess and adaptedto enter the groove in the shank 64. The lug and groove constitute oneform of bayonet joint. Preferably a spring 70 is arranged in the stem 6,toengage the upper end `of theshank 64 and press it normally outwardly,thus retaining the parts in their lease the abrasive disk 62 from theholder after the holder has been disconnected from the spindle 2 themember50 and itsattached parts are moved upwardly on the stem A6 bymanipulating the nut 52,' thus unclamping the diskas shown in the righthand view of Fig. 5.' The securing device 60 may then be turned Slightlyand` pressed upwardly against the spring 70 until the groove 65 is inalinement with the stud 68, when the securing device may be withdrawnand the disk 66 slipped off from it. A new abrad" ing device is appliedby threading it upon the shank 64. The securing device is then pressedinto the stem 6`and turned to lock it in position, and then the memberand its attached parts are forced downwardly on the' stemto Aclamp thedisk against the head of the securingdevice'.. Among the advantages ofthis holder may be mentioned the provisionfor unclamping the abrasivedisk by raising the member v50, before the securing device. ismanipulated for withdrawing it., and the provision by which the securingdevice may be readily detached from the coperating clamping member and Ithe abrasive disk then threaded over the` stem of the securing device.This latter provision makes itunnecessary to provide a large opening inthe abrasive disk or to slit and thus weaken the disk, as has beenheretofore proposed, in order to enable it to be applied over thehead ofthe securing device. Y

In Fig. 12 is illustrated a modified form of holder in which the stem 72is provided on its lower endwith a member corresponding in function tothe securing device heretofore described, said member comprising a shankportion 74 of less diameter than the stem and a clamping head 7 5.` Theshank 74 is preferably rigidly attached to the stem 72. Coperating withthese parts is a clamping member corresponding in function to theclamping member heretofore described as including the parts 50,- 58, 59.This clamping member comprises a sleeve 76 and an attached felt disk 77.The sleeve is movable longitudinally and also rotatively upon thestem.72 and is provided with a stud 78 which extends into a groove 8O inthe stem 72. A spring 82'is arranged between a shoulder on the stem 72and a shoulder on the sleeve 76 to force the sleeve downwardly and'thereby clamp an abrading device `between the felt disk 77 and the head7 5. Preferably means'is provided for assisting the spring 82 to' movethe sleeve- 7 6 in the direction for clamping the abradand 2.

'ing device while the machine is in operation. As herein shown, the stem72 1s rovided with an inclined Vface 84 ex'ten ing laterally from thegroove 80 and in posi ion for Hfllgagement, with the stud 78 when thestem is rotated in the direction of the arrow. It will' be understoodthat the resistanceI to the rotation .of-the holder by reason 0j theengagement of the abrading device with the stock will tend to turn thesleeve and the stud 78 against saidy inclined face and the sleeve willthus be forced downwardly. Then it is desired to remove an abradingdevice the sleeve 76 is turned to bring the stud 78 into -alinement withthe groove 8O land then is raised against the pressure of the spring 82to unclamp the abrading device. Preferably 'provision 1s made forholding the sleeve 76 in its raised position and for this purpose thestem 72 is herein shown as provided with a laterally ofse seat 86'opening from the groove 8O an adapted to receive the stud 78 when thesleeve has been raised and turned slightly. Thestem 72 may be formed atits upper portion to be connected to the spindle'as is thc stem 24 inFig. 7 or the upper end of the stem 72 might obviously be shaped likethe stem 6 to adapt it to be connected to the spindle in the wayillustrated in Figs. 1

.In Figs. 7, 9, l0 and 11 is shown a holder adapted to support anabrading element which comprises a pad 87, and an abrasive covering 88the marginal portion of which is turned upwardly an inwardly over thepad and clamped in position upon the upper surface of the pad wherebythe edge as well as the lower face of the pad is coveredbyabrasivematerial. In this construction the holder comprises an upperclamping member 90 which is vertically movable upon the stem 24. Asherein shown the clamping member is screw-threaded directly to the stem,but it is obvious that it might vbe arranged for adjustment along thestem in the same manner as the member 50 shown in Fig. 5. Coperatingwith the clamping member 90 is a securing device comprising a head 92and a shank 93. The shank extends upwardly into a central opening` inthe stem 24 and is provided with a recess 94 to be engaged by aspring-pressed pin 95 which is mounted in the flange 42 with which thestem is provided as before described. A spring 96 is arranged in thecent-ral opening in the stem and engages the upper end of the shank 93to force the securing device downwardly and outwardly when the lockingpin is withdrawn.

In the use of the machine the spindle may be continuously rotated andwhen the abrading device carried by the holder becomes worn or for anyother reason requires to be changed the holder may beinstantly'disimacat the handlever 20- or 20, shown in Figs. 1

I is.

and 2, or lthe lever 32k of the construction shown Fig..7. When theupper end of the lever 20 or 20*l is moved outwardly the lower arm isput into the path of the latch which, in the rotation ot the spindle,'will engage said; device and be moved to withdraw 'the `coupling pin 14and thereby disconnect the hol er from the spindle.- As soon asl theholder disconnected it will move downwardly and thus be detached fromthe spin-l dle.

If, as shown in Fig. 2 the latch is carried.'

by the holder the engagement ofthe hand lever and latch will check therotation of theholder as soon as it is disconnected from the spindle.this figure the hand lever not only effects the disconnection of theholder and spindle but separates the holder from the spindle byengagement with the inclined face 13 of the latch. It the embodiment ofthe invention shewn in Fig. 7 is employed the lever 32 may be depressedat any time while the machine is running to raise the spindle andseparate the clutch members 25, 26, thus disconnecting the holder fromthe spindle. When the lever 32' is depressed the latch 38 willautomatically engage the shoulderr 40 and hold the spindle in its raisedposition with the clutch members apart. The clutch member 26 which iscarried by the holder has an extended contact by its lower face with thebearing in which the holder rotates and when the holder is. disconnectedfrom the spindle the friction between the clutch and the bearing assistsin checking the rotation of the vholder and bringing it incre promptlyto rest.

To replace an abrading device in the holder shown in Figs. .1, 5 and'6the. nut 52 is actuated to move the clamping member 50 upwardly on thestem of the holder, thus releasing the grip on the abrading device,after which the securing device may be easily turned and moved upwardlyas is necessary to disengage its seat 66 from the llug 68 on the stem.,thus bringing the groove 65 inte alinement with'said lug. When this hasbeen `done the spring 70 will expel the securing device and the Wornabrasive disk may be taken from the shank of the securing device and anew disk put into place. The parts may then be reassembled by thrustingthe securing device into place and turning 1t to interlock it with thelug on the stem 6 and thereafter moving the clamping*` member 50downwardlyto bind the abrasive disk between the head 60 and the feltdisk 59.

In using the holder shown in Fig. 12 the sleeve 76 is turned to bringits stud 78 into alinement with the groove 80 in the stem 7 2 and thenis moved u wardly on the stem against the tension o the spring 82 afterIn the construction showgn in lwhich it may be locked in its raisedposition 'by turning it to engage th'e stud 78 with the lnotch 86. Theabrading device may then be removed by ldrawing 1t over the head 75 anda new device put into place. When the sleeve 76 is next turned to putthe stud into alinement with the groove 80 the spring 82 will force thesleeve downwardlyto vclam the: abrasive disk against. the head an in therotation of the holder the stud 78 will engage the inclined face 84 andcause the abrading device to beclamped with 'a to rotation encounteredby said device. It is to be noted thatv inthis construction the abradingdevice is automatically clamped -when the spring 82; is permitted to actand that the force with whlch the device is held is automaticallyincreased by strains tend-u ing to. turn the abrading device in the`holder.

- pressure which increasesy with the resistance In the. use'tof theholder shown in Figs.

17 9,. 10, and 11 the holderr is not removed from the machine, but afterithas been disconnected from the spindle the clamping member will bemoved upwardly on the st'em 24:, thus releasing the abrasive covering,and if desired the locking bolt may be withdrawn from the shank 93 ofthe securing device and the spring 96 will expel .thesecuring devicefrom the stem.
